Most electric loads in homes don't run on out-of-phase power. Appliances such as stoves, ovens, toasters and electric heaters use in-phase voltages and currents to produce heat. For appliances with motors, such as fridges, washing machines and dryers, the motors are either too small to ma...

This 3-phase power calculator determines the active, apparent, and reactive power from known RMS voltage, current, and power factor for a symmetrical three-phase system with a balanced load. Example: Three equal inductive loads with a power factor 0.68 are connected in star to a 400 V (line...
很多朋友在制作 Power BI 的时候都会被后面的一些可怕的纠结的报错弄得头昏脑胀,经常一找就是找好几个小时。能找到错误还算好的,可怕的是无疾而终,就此作废,推倒重做。 在编程里面有一个报错原则,它告诉我们: 报错要早 报错要猛烈 为什么要早呢?因为一个错误如果不处理,越拖到后面引发的错误就会越多、越复杂...

This paper evaluates various power formulas for flow resistance in open channels. Unlike the logarithmic resistance equation that can be theoretically derived either from Prandtl's mixing-length hypothesis or von Karman's similarity hypothesis, the power formula has long had an appearance of empiricism...
